MODULAR MOTOR DRIVEN SURGICAL INSTRUMENTS WITH ALIGNMENT FEATURES FOR ALIGNING ROTARY DRIVE SHAFTS WITH SURGICAL END EFFECTOR SHAFTS

摘要

Coupling systems for removably coupling dual rotary drive shafts of a surgical instrument to corresponding driven shafts of a surgical end effector. The surgical instrument (10, 10' , 310, 410, 610, 710, 800) may include a first rotary drive shaft (22, 522, 622, 722, 803) that includes a first drive shaft axis and a second rotary drive shaft (40, 640, 740, 807) that includes a second drive shaft axis. The second drive shaft axis may be offset from and parallel with the first drive shaft axis. The coupling systems may facilitate simultaneous operable attachment of the first and second drive shafts of the surgical instrument with corresponding first and second driven shafts of a surgical end effector (1000) such that rotation of the first drive shaft rotates the first driven shaft and rotation of the second drive shaft rotates the second driven shaft.
